How to Call a Controller method from a Link in a View in Laraval?

Blocked by the fact that OVH can't deploy .Net websites we have turned to use Laraval (in order to use MVC).

so I have created a controller and I need to call it's methods from my layout, I tried this :

<a class="nav-link" href=""><span style="text-decoration: underline;"><B>Acceuil</B></span></a>

where HomeContoller is my controller and WhoWeAre is a method .

when I run my app , the website crash and I get this message :

ErrorException in UrlGenerator.php line 589: Action App\Http\Controllers\HomeController@index not defined. (View: C:\xampp\htdocs\laravel\resources\views\welcome.blade.php)

How can that be corrected please ?
